Coronary Artery Disease
Assessment of Coronary Artery Stenosis by Coronary Angiography
A Head-to-Head Comparison With Pathological Coronary Artery Anatomy.
Between July 2004 and December 2011, 97 patients underwent CCA within 15 days before heart transplantation in Fuwai hospital. A head-to-head comparison study was performed to examine the diagnostic accuracy of CCA as compared with that of pathological coronary artery anatomy.
Per-segment evaluation found CCA was more accurate for detecting ≥50% and ≥75% stenosis in proximal and middle segments than in distal segments, and the diagnosis ability decreased in more severe stenosis segments and more complex lesions.
Conclusions—The accuracy of CCA is quite high in detecting coronary artery stenosis in patients- and vessels-based levels. However, the diagnosis ability decreased in more severe and complex lesions, especially for distal segments.
Estudo inteligente e bem executado mostra que o Cateterismo é muito fraco como método para afastar isquemia. Muitos ecostresses positivos que foram confrontados com cateterismos "normais" podem ter até 50% de chance de ser uma lesão distal mal avaliada pelo exame de coronariografia.
